    摘要: The invention concerns a method for controlling the operations of a wind farm having a group of at least two wind turbine generators (WTG's) of asynchronous fixed speed generator type each connected to a frequency controlled WTG Grid by the principle of an electrical torsion shaft. The invention is carried out by collecting reference data/information of individual WTG power production at different wind speeds and different turbine rpm, collecting at least one actual WTG Grid related parameter value, collecting at least one individual operational performance-related value of two or more WTG's, determining, based on said collected values and stored reference data/information, the necessary change of the WTG Grid frequency (collective turbine rpm) for achieving the desired change in collective performance result such as optimizing the power production, avoiding structure/rotor resonance etc. and generating control signals for directly, or indirectly through a Grid Control Device, adjusting the actual WTG Grid frequency. The invention also concerns a system, a control device and a computer program for controlling the operations of the wind farm.

    摘要: Die Erfindung betrifft ein Verfahren und eine Windenergieanlage mit einem Windrotor (3) zum Antreiben eines Asynchrongenerators (4) zur Abgabe elektrischer Leistung an einen Transformator (9). Die Erfindung sieht vor, dass der Transformator (9) mit zwei Primärwicklungen (91, 92) versehen ist, und der Generator (4) über einen Umschalter (8) je nach Betriebsart mit einer der beiden Primärwicklungen (91, 92) verbunden wird. Damit kann eine Verschiebung der Betriebskennlinie der Windenergieanlage erreicht werden. Somit kann die Kennlinie nach unten hin zu Schwachwindbedingungen verbessert werden, ohne dass dafür der herkömmlicherweise erforderliche Zusatzaufwand anfällt.
